Wood for Resisting Fires

1896

A report from Consul Robertson on the free port system of Hamburg, just published by the State Department, contains the curious item of information that in the great new warehouses constructed in the German port wood is being substituted for iron to secure better protection against fire.

These buildings were originally provided with iron beams and girders, but when one of them was burned some years ago it was found that the iron had been so bent and twisted by the heat as to become a source of great danger to the adjoining structures. "In all the warehouses, therefore, which have since been built," observes Mr. Robertson, "it has been deemed advisable to substitute wood for iron as much as possible." Probably a heavy wooden beam, imbedded in some non-conducting material that would exclude the air, would be as nearly fireproof as anything except brick or stone. It might be charred on the outside, but the interior would probably remain sound in any ordinary heat.

It is a curious speculation to imagine what would have happened if the present method of construction in Chicago had been in vogue before the great fire. A twenty-five-story, steel-cage building warping into a corkscrew and boring a hole in the sky would be a spectacle worth going miles to see.


Derivation of Whiskers

The word whiskers is derived from whisk, and the Anglo-Saxon wisch, which means a slight brush. Less than a century ago the expression was unheard of, the whiskers as well as the mustache being spoken of as part of the beard. It was only when the latter was divided, and the true whiskers disappeared as well, that their name was changed to the mutton chop part of the beard left on the cheek.
